Conservation agricultural practices for minimizing ammonia volatilization and maximizing wheat productivity.

A large amount of ammonia volatilization from the agricultural system causes environmental problems and increases production costs. Conservation agriculture has emerged as an alternate and sustainable crop production system. Therefore, in the present study, ammonia losses from different agricultural practices were evaluated for the wheat crop under different tillage practices.

Constitutive production of extracellular glucose isomerase by an osmophillic Aspergillus sp. under submerged conditions.

We report constitutive production of glucose isomerase (GI) under submerged growth of Aspergillus sp. in glucose phosphate broth (GPB). The fungus produced significant quantities of extracellular GI in GPB without supplementing the inducer (xylose).
